From what I can see there is nothing wrong with the code. Your issue is because you are trying to access a URL which is not available, since it is not yet exposed to the internet.

Just for the sake of testing that there is nothing wrong in the url, I recommend changing 192.168.7.175/app/app.html to a more plausable website such as http://www.google.com for the time being.

Your next step is to find a way to expose your website to the web, so that it is accessible from your device. If you have IIS installed, you can copy your website content to the C:\inetpub\www folder. This would expose (make it available on the web) your site to anyone knowing the url. You can also use this tutorial to help you.

  try this:
        //if you have your html file in assets folder do like this
        // aboutWebview .loadUrl("file:///android_asset/About.html");
        WebView aboutWebview = (WebView) findViewById(R.id.aboutus_webview);
        aboutWebview .loadUrl("http://192.168.7.175/app/app.html");
        WebSettings webSettings = aboutDmrWebview.getSettings();
        webSettings.setJavaScriptEnabled(true);
        aboutWebview .addJavascriptInterface(new JavaScriptInterface(this), "Android");
        aboutDmrWebview.setWebViewClient(new MyWebViewClient());


      private class MyWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        if (Uri.parse(url).getHost().equals("www.google.com")) {
            // This is my web site, so do not override; let my WebView load the page
            Toast.makeText(getApplicationContext(), "www.google.com", Toast.LENGTH_SHORT).show();
            return false;
        }
        // Otherwise, the link is not for a page on my site, so launch another Activity that handles URLs
        Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
        startActivity(intent);
        return true;
    }
}

Did you add this line in your manifest file ?

<uses-permission android:name="android.permission.INTERNET" />
